Practical Vegetable Protein Sources

[wantonebad]

Hi guys,
Thought I would ask this question of our esteemed membership considering we all have expertise in so many different areas. I'm looking for some alternate sources of lean protein, preferably vegetable based, that I can add to smoothies and to meals. I'm not going vegan, or swearing off whey or soy but men should really go easy with their soy intake as it can mess with estrogen levels. Whey protein has it's own set of drawbacks that I would like to avoid. I've been using a combination of Hemp and Amaranth proteins and they are good, but I'd love another source that's maybe a bit cheaper, Hemp protein powder is crazy expensive, and Amaranth is so esoteric healthfood stores can charge whatever they want..
